ASTM C273/C273M, Standard Test Method for Shear Properties of Sandwich Core Materials, is the test method for shear properties.
ASTM C273/C273M Standard Test Method for Shear Properties of Sandwich Core Materials
At a Glance
Document type: Test Method.
Edition: active, current edition C273/C273M-20.
Property determined: shear properties.
Scope
Determination of shear properties of sandwich construction core materials associated with shear distortion of planes parallel to the facings: shear strength parallel to the plane of the sandwich, and the shear modulus associated with strains in a plane normal to the facings.
Permissible core forms include continuous bonding surfaces such as balsa wood and foams, and discontinuous surfaces such as honeycomb.
What the Result Tells You
A test to ASTM C273/C273M characterises the shear properties of the material or assembly under the conditions the method fixes: specimen form, rate of loading and the environment in which the test is run.
Because the numbers depend on those fixed conditions, a result is only meaningful when the report names the standard, the edition and any options the method allows.

Reading the Designation
ASTM C273/C273M: a dual designation. One half carries the inch-pound version and the other the SI version. The two systems are used independently, never mixed inside a single report.
When a drawing, purchase order or quality procedure cites this document, the test setup, the specimen and the report follow that citation.
